ci: add build workflow for main branch

Build and push multi-arch container images (linux/amd64, linux/arm64) to GHCR and Docker Hub on every push to main that changes Go or Nix files. Images are tagged as main-<short-sha> using ko with the same distroless base image as release builds. Cross-compiled binaries for linux and darwin (amd64, arm64) are uploaded as workflow artifacts. The README links to these via nightly.link for stable download URLs.
